Product Description
Siemens 255-01114 is a globe valve assembly with a direct-coupled electromechanical actuator configured as a two-way, normally closed control valve for 1 in NPT piping. It provides a 10 Cv flow coefficient with brass trim, ANSI Class 250 body rating, and a 200 N non-spring-return actuator operating at 24 VAC/DC with 2.0 VA and 0-10 VDC modulating control. Rated NEMA 1, it is suitable for water and glycol solutions up to 50% and operates between 1 C and 50 C.
